Bug # sorting TypeError fix

Review Request #1168 - Created Oct. 8, 2009 and submitted

Review Board
When entering multiple long numbers in the bug list of a review request, posting the request resulted in a TypeError. This patch should correct the issue.
Tested with a local Review Board installation. Numerical and lexicographical sorting still work correctly after applying the fix. Large bug # no longer trigger a TypeError.

  1. Thanks. Committed along with a unit test to master as r10b5857.

  1. I do not like the implementation:
    >>> bugs=['123456789123456789','89']
    >>> bugs.sort(cmp=lambda x,y: int(x) - int(y))
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: comparison function must return int, not long
    The proper way is to use python's function "cmp":
    >>> bugs=['123456789123456789','89']
    >>> bugs.sort(lambda x,y: cmp(int(x),int(y)))
    >>> bugs
    ['89', '123456789123456789']
  2. reviewboard/reviews/models.py (Diff revision 1)
    Very dodgy hack.
    This would not handle the case when the difference between x and y is a long number.
    The correct way is as follows:
    bugs.sort(lambda x,y: cmp(int(x),int(y)))
    1. Yeah, you're right. Fixed and updated the unit test to better check comparisons of longs with long results.
